Abstract
Abstract Background& purpose: Apoptosis is a progressive disorder in diabetes that gradually affects nerves and tissues. Lifestyle modification is one of the approaches to combat diabetes-related complications, which is why exercise and proper nutrition have always been emphasized by specialists. This study investigates the effect of 6 weeks of endurance training combined with spirulina supplementation on the expression of apoptosis-inducing factors in the hippocampus of streptozotocin-induced diabetic rats. Methods: A total of 28 male Wistar rats were divided into 4 groups by intraperitoneal injection and a single dose of streptozocin (50 mg/kg) including: 1. Diabetes control group, 2. Diabetes + Spirulina group, 3. Diabetes + Exercise group and 4. Diabetes + Exercise + Spirulina group. The exercise program of the exercise groups started for 20 minutes at a speed of 14 cm/s and continued for 45 minutes at a speed of 24 cm/s until the sixth week. Spirulina was administered at a rate of 500 mg/kg body weight via gavage. 48 hours after the last exercise session, hippocampal expression of proBDNF/p75NTR and NF-κB genes was evaluated by RT-PCR method and statistical analyses were performed using SPSS-23 software and one-way ANOVA method. Results: The intervention methods caused downregulation of the studied genes compared to the diabetes control group. A significant decrease in proBDNF and NF-κB expression at the p≤0.001 level and p75NTR expression at the p≤0.01 level was observed in the combined exercise group compared to the diabetes group. There was a difference between the single intervention groups only in p75NTR expression (p≤0.05). Conclusion: Endurance exercise and spirulina supplementation effectively regulate apoptosis in diabetes, suggesting potential benefits in mitigating neurological, metabolic, and cognitive impairments in diabetic patients.
